Still trying to decide what to go with, the Bafang or the Tongsheng for my build. I understand the fundamental differences between the Bafang PAS and Tongsheng torque sensing the latter being more appealing to me. I see that some versions of the Tongsheng have a throttle and the literature I have found says that this function is limited in power. But how limited?? Speaking about the US model motor programmed for 750 watts. Nice to just ride with throttle when needed or when not wanting to exercise and get sweaty.
